If you are using an email client such as Microsoft Outlook, Mozilla Thunderbird, or Apple Mail, you may come across an issue where your email messages:

• Cannot be sent but can be received
• Cannot be received but can be sent
• Cannot be sent nor received

(There are no issues when you access your email from a web browser.)

To solve the problem, try the following:

• Change the outgoing and incoming mail ports your email client uses. Our service blocks traffic over the insecure port 25, so use other commonly used e-mail ports such as 587 or 465
• Disable the ThreatBlock feature in the application settings
• Switch to a different NordLayer server. Your email provider may be blocking access to its email services from IP addresses of a known VPN server. Switching to a different NordLayer server may help

If none of the above solves the issue, please contact our customer support team and let them know which methods you have already tried.
